Her exit extended a multi-year pattern of senior safety-leadership departures from OpenAI.

Policy researcher who resigned after the dissolution of the AGI Readiness team and the departure of her manager Miles Brundage, writing that she had been "unsettled by some of the shifts over the last ~year, and the loss of so many people who shaped our culture."

In a sworn 2025 declaration supporting an amicus brief filed by twelve former OpenAI employees, he said he had 'realized the charter had been used as a smoke screen — something to attract and retain idealistic talent while providing no real check on OpenAI's growth and its pursuit of AGI.'

Departed in early June 2024, the same week he helped organize the public 'Right to Warn' letter demanding that AI-lab employees be free to raise safety concerns.
